Telegram bot for HR automation: screening, scheduling, and onboarding

Our HR team spends approximately sixty percent of their time on routine tasks — correspondence with candidates, coordinating interview times, collecting documents, and conducting the same introductory process for each new hire. We want to hand over this routine to a Telegram bot so that people can focus on decision-making rather than coordination. The bot should fully cover three stages: initial candidate screening, interview scheduling, and structured onboarding for those starting work.

Screening begins with job vacancy distribution to subscribers and running candidates through a role-specific quiz: answers are automatically scored against a threshold, and the recruiter sees a clean digest of suitable candidates with attached resumes. Interview scheduling works through Google Calendar — the bot displays actual available slots, sends invites to both parties, and reminds everyone before the meeting, neatly handling rescheduling and cancellation. Onboarding runs a 30-day checklist for each new hire: daily reminders, collection of signed documents directly in the bot, and notifications to the manager at key points — day 1, day 7, and day 30.

On top of the bot, we need a small web panel: job vacancy and question management, pipeline overview and onboarding progress, report exports. Stack: Python (aiogram 3), PostgreSQL, Redis, Google Calendar API, AWS S3. Fixed budget — 600 USD for 25 days. In your response, tell us about a bot of comparable complexity.
